Two new Oreo flavors are coming to a cookie aisle near you. The iconic sandwich cookie is adding marshmallow crispy and cookie dough as limited-edition flavors next month.

The announcement was made Thursday morning on ABC's Good Morning America, along with the announcement that viewers who watch the Grammy Awards on Sunday night will see a new Oreos commercial that will contain a special hashtag that cookie-lovers can tweet to snag some freebies before they arrive in the grocery store.
